One British diver was lucky enough to catch a glimpse of one of the ocean’s most elusive sharks—the megamouth. Penny Bielich was diving at Gili Lawa Laut on Indonesia’s Komodo Island when she saw the creature and captured it on video.

The mysterious looking mammoth shark can be seen swimming shockingly close to the camera in a video uploaded to YouTube Wednesday.

Bielich was one of the rare people to have ever seen a megamouth shark, let alone got up close and personal with one. Only about 60 sightings of the creatures have been confirmed in the past 41 years, according to National Geographic. The bizarre sharks were first discovered in 1976 and were considered so strange at the time that scientists categorized them in a brand new genus and family.

A U.S. Navy ship was responsible for the first ever discovery of the shark after accidentally capturing one in parachute-like nets off the coast of Oahu in Hawaii.

“When the parachutes were hauled up, they discovered that one had entangled a large shark, now dead, that no one recognized,” Sharkopedia reported. The 14.6-foot shark was shipped to the Waikiki Aquarium, where it was dubbed Megachasma pleagios, or "huge yawning cavern of the open sea."

Due to relatively few sightings of the shark, much remains unknown about the creatures. The filter features can grow up to 17-feet long and have "a soft, flabby body and poor swimming skills," according to the Florida Museum of Natural History. Beyond that, little is known.

The International Union for Conservation of Nature considers the species "data deficient" because so few had ever been studied. The Discovery Channel called the creature "large and eerily majestic" and dubbed it the "alien shark."

In one of the most notable incidents of megamouth shark spotting, one of the creatures was captured by fishermen in the Philippines in 2009. The 13-foot-long shark, nicknamed "Megamouth 41," was given to butchered by local fisherman to be served in a shark meat dish.

"While it is sad that this rare megamouth shark was ultimately lost, the discovery highlights the incredible biodiversity [of the region] and the relatively good health of the ecosystem," World Wildlife officer Yokelee Lee told National Geographic at the time.
